Cheap Oscilloscope US$64

[der_fisherman]

Have a look here:-

http://tronixstuff.wordpress.com/tag/gabotronics/

It is an O'scope, arbitrary waveform generator, logic analyser and a spectrum analyser – including a display – in a package no larger than 25.4 x 40.6 mm (1″ x 1.6″) in size.

It costs US$64.00 and may be interesting for some of you with only elementary test equipment. I have not bought it as I am quite well off for test tools, but if I was not, I would buy it!!!

Best of luck.

Interesting piece of technology.

Nothing about analog channel input sensitivity?

(I cannot connect to producer website for more info)

A truely amazing peice of kit!!! gotta have one!!!

WM6: the their website is working now.

Mini Scope

If anyone buys one we all need a full test from you.

WARNING.
The manual is physically larger than the device itself!!!

Here it is!!

Thanks TH Jim.

500mV max sens per channel.

Expected a little better sens, but otherwise very capable toy even with FFT.

Man O Man!

That's got to go on a detector some place!

That little puppy could go on so many projects you can't even list them.

Hello ,
i must put my big eyeglasses to see something !!!! and worst in sun field !!!!
Much better Samsung tablet with android and aps

There only $49.00 here!

Xprotolab and Xminilab

Hi, this is Gabriel, the designer of the oscilloscopes being discussed here.

I wanted to thank you for your interest and also do some clarifications.

- I currently have two version of the oscilloscope, they both have the same features, but different display sizes, the small one (Xprotolab) costs $49, the larger one (Xminilab) $64:



- The maximum channel sensitivity is 80mV/div, one division consists of 16 pixels, (5mV per pixel). Not sure where the 500mV mentioned before came from...

I'll be happy to answer any other question

Hi Gabriel, welcome to the forum,... that looks a super piece of kit you have put together,... I guess the frequency range is pretty much audio, would that be correct????

Still, a nice thing to play with,... and sure some of the guys on here will buy them,

Cheers, Fred

Frequency

The bandwidth is 200kHz. The maximum sampling rate is 2MSPS.

So you can still observe signals up to 1MHz, but the amplitude will be attenuated.

Thanks Gabrijel,

for clarifications and congratulations for your great work.

80mv/div sound much better, but I cannot found those data in your brochure, I only found 0.5V that was alike max input sensitivity.

Vertical Sensitivity

Thanks, I have updated the manual, now it shows the vertical sensitivity on the specifications.

Dear Gabriel,
firstly many thanks for the clarifications you gave us and congratulations on what appears to be an interesting product for many of us here.
Luckily for us, we are generally concerned with relatively low frequencies with metal detecting and the frequency range you mention would normally be more than enough.
I for one am interested in using the unit as a VLF (under 20KHz) Radio Spectrum Analyzer. I want to see where various transmissions are placed within that range of frequencies and their relative values in terms of signal strength as I am a believer that part of the problem with sensitive VLF metal detectors may come from outside interference, especially in the 50 to 60 Hz bands (depending on the voltage frequency where you live). This seems to possibly adversely affect our machines, though nothing fully proved as of now.
I want to build some sort of "receiver", possibly using a metal detector coil without shielding, but with some sort of circuit to keep the output to a level that you unit can accept, probably including two diodes, reversed, to keep the max input under 600mVolts, but with some sort of amplifier control to all setting to the highest signal/frequency received and leaving all the others at their "relative" values....Also to be able to expand certain areas of interest to examine them better.
I am asking probably too much.......but hopefully it would work for both audio and Radio with the correct front end.......maybe you have something already half developed?
Regards
Andy
PS. It was I who "stumbled" on your unit while reading a German electronic magazine. I attach a picture for your collection!!!

Hi Andy,

from scope viewpoint there is no difference if signal of the same frequency and shape is comming from audio or radio source.

For what you asking some sort of audio equalizer between receiver and scope will done job well.
